Ultra-Discreet Earbuds for Sleep and Work
The CNBRO SK19 earbuds are an ultra-compact in-ear model designed to sit almost flush with the ear canal. Their low-profile shape targets side sleepers and professionals who need audio that stays hidden during calls or rest. Balanced armature drivers deliver sound across a 20 Hz to 20,000 Hz range with 10 ohm impedance.
Four-Hour Buds with Twenty-Hour Case
Each charge provides 4 hours of continuous playback from the buds themselves. The charging case holds an additional 20 hours, reaching a combined 24 hours before you need a wall outlet. Bluetooth 5.3 handles the wireless link, and the case recharges fully in about an hour. Sound isolation passively reduces background noise without active circuitry.
Tiny IPX-Rated Shells with Touch Controls
The plastic earpieces measure 3.23 cm by 1.61 cm by 4.2 cm and carry a water-resistant rating for sweat or light rain. Touch surfaces on the buds manage volume and playback directly, removing the need to reach for a phone. A built-in microphone supports calls, and the package includes a single pair of ear cushions for fit adjustment.

Questions about this item
How do I pair these SK19 earbuds with my phone using Bluetooth 5.3?
Open the charging case lid, then select SK19 from the Bluetooth menu on your smartphone, music player, computer or tablet; the earbuds enter pairing mode automatically when removed from the case.
What part of the SK19 will wear out first and need replacement?
The built-in lithium-ion cells in each earbud and the charging case lose capacity over time; after many charge cycles the 4-hour per-charge figure will drop noticeably.
What stops the SK19 from playing continuously during a long work shift?
Each earbud holds only 4 hours of charge, so the first limit you hit is the earbud battery running flat; the case adds 20 hours total but you must pause to recharge.
